A girl who is so skinny you think someone aught to stop and give her a samich. Generally meant to be descriptive rather than an insult or compliment. Derives from a decriptive conversation; you know that skinny girl, we're talking real skinny, someone give that girl a samich skinny...

I was at the video store the other day and that samich girl was working again; it reminded me I had to stop at Subway on the way home.
